Candy CDB 754DN
Hi Guys
problem with this washer - it’s empty, drained nothing is blocking the pump but when connected to power near enough all the lights on the front are lit and it’s doing a lot of beeping.
its not looking good - moving the selector isn’t making any difference, pressing and holding buttons like start/pause make the beeping tone change.
any ideas greatly appreciated

Candy CDB 754DN all lights illuminated and constant beeping traced to failed controller board
- The problem
- The Candy CDB 754DN was empty and drained, with nothing blocking the pump, but when powered on nearly all front panel lights illuminated and the machine emitted repeated beeping. The programme selector made no difference, although pressing and holding buttons altered the beep tone.
- Likely cause
- Failed controller board. This was strongly supported by scorch marks on the PCB and a blown resistor found on the removed board.
- What fixed it
- The controller board at the back bottom left of the machine was removed and replaced with a new board. After fitting the replacement, the machine powered on and off normally and no error codes appeared.
- Checks to try
- Confirmed the machine was empty and drained
- Checked that nothing was blocking the pump
- Observed nearly all front panel lights lit with repeated beeping
- Observed selector movement made no difference
- Removed the controller board and inspected the PCB
- Found scorch marks on the underside of the PCB
- Found a blown resistor on the board
- Checked for any other visible blown components after replacement and found none
- Parts or tools mentioned
- Replacement controller board
- One bolt-head screw
Safety: Disconnect the appliance from the electricity supply before any inspection. Work involving mains electrics, gas or sealed refrigeration systems should only be carried out by a suitably qualified appliance engineer.

Hello there. It's not usually a good sign when all of the lights do that. It's not something that is supposed to happen. Modern washing machines are supposed to indicate specific error codes by displaying the actual code on models that have a display capable of displaying letters and numbers. On models that don't have a display they should indicate by flashing specific option buttons. Unfortunately I don't have Candy error codes at the moment. It might be possible that the 3 lit option lights are indicating a code.

Hi Guys
i want to update this thread for any future users. I took the controller board out located at the back bottom left hand side held in place with one bolt head screw.
disconnecting is fairly straight forward but the cables can be quite stiff to remove.
the old board has scorch marks on the bottom of the pcb - take the board out of its plastic housing to see the chip side where the washer memory and resistors are located I found a resistor had blown.
replacement board was ordered from a candy / Hart parts stockist in Italy I couldn’t find them anywhere else.
board was shipped and well packed with DHL and took 5 days.
Installed the board double checked anything else which could have possibly blown and couldn’t see any issues elsewhere the board has solved the issue above that I originally posted after install I didn’t receive any error codes so I was hopeful that meant nothing else had blown.
im 4 washes in now without any issues unit turns on and off fine.
price of the controller board for this unit after currency conversion was £66.90
cheers - Marc
